RPI 2 Debugging not working.

Postby arunmag » Sun May 14, 2017 5:40 am

I am using Raspberry Pi 2 B running raspbian and i have followed this tutorial https://movr0.com/2015/10/15/how-to-jta ... om-kernel/
How do i enable the JTAG and debug it?
I am on Lubuntu 17 with FT232H JTAG adapter. But i am getting this weird error.
